Abstract

The invention relates to a high-frequency torsion-restoration axial vibration impacting tool for well drilling engineering of petroleum and natural gas. The tool is connected to the upper portion of a drill bit in a threaded mode and comprises a turbine assembly, a switching assembly and an impacting assembly. The front end of the switching assembly is connected with the impacting assembly, the rear end of the switching assembly is connected with the turbine assembly, and periodical change of a mud channel is achieved through the switching assembly; and a sliding sleeve is pushed to slide forwards through the differential pressure generated by flow channel change, axial displacement and acting force are generated to act on an impacting spline for driving the impacting spline and an impacting hammer to move forwards together, a torsional spring at the front end of the impacting hammer is compressed, an anvil is impacted by the impacting hammer, when the sliding groove moves backwards, the torsional spring exerts a rotating torque on the impacting hammer to enable the impacting hammer to rotate, and after the impacting hammer enters another spline groove, periodic movement is repeated. The high-frequency torsion-restoration axial vibration impacting tool is simple in structure, high in adaptability for the drill bit and the stratum and capable of improving well drilling efficiency.

Description

technical field [0001] The invention relates to a high-frequency torsional reset axial vibration impact tool used in the field of oil and gas drilling engineering. Background technique [0002] With the continuous development of the economy, the demand for oil and gas is increasing, while my country's shallow oil and gas resources are increasingly depleted, oil and gas exploitation will inevitably develop in the direction of deeper and harder formations, and my country's deep oil and gas reserves are quite rich, making it difficult to exploit oil and gas resources also gradually increased. Therefore, the formations drilled by oil and gas drilling will become deeper and deeper, the geological age will be longer and longer, and the rock will become harder and harder. However, the level of drilling technology limits the development of deep wells and ultra-deep wells. Improving the drilling speed of deep wells in hard rock has become one of the important topics in the drilling i...
